Status

  • Aug 2001
    Core updated and some more bugs fixed. It is now being verified more thoroughly but it is mostly usable.
  • 27.05.2001
    Documentation and core code are updated.
  • 17.05.2001
    The core is finished unless more bugs are found.
    The test bench is very basic yet and is asking for your help to expand it. :-)
  • 26.01.2002
    The core is functional in polling mode, checked on FPGA.
    Should be functional in interrupts mode too but not verified fully in hardware.
    Monitor debugging feature is added
    All known bugs fixed.
  • 28.01.2002
    The core is functional in all modes (interrupt and polling mode), checked on two different boards.
    Full operational in uCLinux using included 16550 driver.
